Thanks Steameister! I’ll actually be in Orlando in September, hoping to try a wand prototype then. So jealous that you get to have butterbeer all of the time.
My thoughts on the whole situation:
The wands work by reflecting IR light. A camera picks up the light being reflected, tracks it, and then checks to see if it performs the right sequence. All of that is based off of this image from the patent: https://patentimages.storage.googleapis.com/US20140240102A1/US20140240102A1-20140828-D00003.png
Could you potentially make your own ‘electronic’ wand by hooking up an IR led in series with a battery and a current limiting resistor? It will technically emit light which will be picked up by the cameras. This is my current game plan for my upcoming trip.
